  • Abstract
    An accelerated Kaczmarz algorithm with projection adjustment (KAPA ) and its randomized version (RKAPA) have been proposed in this paper. At each iteration of KAPA, an inertial term is added to make further adjustment on the projective solution on the hyperplane of Kaczmarz algorithm (KA) to accelerate the convergence. Numerical simulations have been conducted. The efficiency of KAPA and RKAPA have been well demonstrated by the simulation results.
